 实现代码

<template><el-dialog class="no-code-dialog" v-model="isShow" title="没有收到验证码？"><div class="nocode-body"><div class="tips">请尝试一下操作</div><div class="wrap"><div class="row"><i></i><span>请确认邮箱地址是否输入正确。</span></div><div class="row"><i></i><span>邮件发送可能存在延迟，请稍等片刻。</span></div><div class="row"><i></i><span>请确认邮件是否在垃圾箱中。</span></div><div class="row"><i></i><span>若问题仍未解决，请联系客服寻求帮助 。</span></div></div></div><template #footer><div class="dialog-btn" @click="isShow = false">确定</div></template></el-dialog>
</template><script setup>
import { ref, computed, defineProps, defineEmits } from 'vue';
const props = defineProps({modelValue: {type: Boolean,default: false}
});
const emits = defineEmits(['update:modelValue']);
const isShow = computed({set(val) {emits('update:modelValue', val);},get() {return props.modelValue;}
});
</script>

样式修改

<style lang="less" scoped>
.no-code-dialog {.nocode-body {.tips {color: #6c6c6c;font-family: PingFang SC;font-size: 14px;font-weight: 600;padding: 30px 0 15px;}.wrap {.row {display: flex;align-items: center;margin-bottom: 10px;i {display: inline-block;width: 7px;height: 7px;transform: rotate(45deg);background-color: #000;}span {color: #000;font-family: PingFang SC;font-size: 14px;margin-left: 10px;}}}}.dialog-btn {display: flex;justify-content: center;align-items: center;width: 372px;height: 40px;border-radius: 4px;background: #000;color: #fff;font-family: PingFang SC;font-size: 14px;font-weight: 500;}
}
// :deep(.el-dialog) {
//   background: #fff;
// }
// :deep(.el-dialog__body) {
//   height: 350px;
//   padding-bottom: 0px;
// }
</style>
<style lang="less">
.el-overlay {.el-overlay-dialog {.el-dialog.no-code-dialog {--el-dialog-width: 420px;--el-dialog-bg-color: #fff;.el-dialog__header .el-dialog__title {color: #000;}}}
}
</style>

.el-dialog.no-code-dialog 添加自己定义的类名用于区分其他组件

});const emits = defineEmits(['update:modelValue', 'onChangeDialog']);
const isShow = computed({get() {return props.modelValue;},set(val) {emits('update:modelValue', val);}
});const closeDialog = (val) => {console.log('onChangeDialog');emits('onChangeDialog', true);
};
</script>
<style lang="less">
.success-dialog {&.el-dialog {--el-dialog-bg-color: transparent !important;.el-dialog__header,.el-dialog__body {padding: 0;}}

 使用

<template><NoCodeDialog v-model="isShowNoCodeDialog" /><SuccessDialog v-model="isSuccessDialog" />
</template><script setup>
import { ref } from 'vue';
import NoCodeDialog from '@/views/Register/components/NoCodeDialog.vue';
import SuccessDialog from '@/views/Register/components/SuccessDialog.vue';
const isShowNoCodeDialog = ref(true);
const isSuccessDialog = ref(true);
